Chu Mia Huang......worse than that....ME!
Ever done a W&B on a 230? or a 170? Two half decent sized aussie guys and you are going NOWHERE! (legally)
540kg limit is a joke when you look at how heavy these little buggers are EWs at around 300kg or more leaves very little for two people and fuel. You have to built like a bludy greyhound to utilise one.
